RADIATOR FOR MOTOR VEHICLES.

Specification of Letters Patent. Pate t d J 17 1922;

Application filed October 17, 1919. Serial No. 331,377.

To all whom it may concern:

Be it known that l, VLADIMIR Bnnvnn, a citizen of the United States, and a. resident. of New York, in the county of Queens and State of New York, have invented certain new and useful Improvements in Radiators for Motor Vehicles, of which'the following is a specification.

The present invention relates to radiators for motor vehicles, that is to say to an appa ratus for cooling the water from the jacket of the engine cylinder.

Radiators for motor vehicles usually comprise an upper water chamber and a lower water chamber, said. chambers being connected by conduits or tubes, through which the hot liquid flows, said conduits and tubes being suitablyspaced, to permit air to move through the radiator. Serious difficulties have been experienced with these devices for the reason that, when any one of the conduits or tubes is injured to an extent that it becomes leaky, the entire radiator is rendered useless, as it must be removed as a whole, from the motor vehicle for purposes of repair.

The main'object of the present invention is to obviate this ditiiculty by building the radiator in sections,'any one of which may be removed, without putting the radiator out of commission.

Another object of the invention is to provide a radiator of the type mentioned which is simple in construction, etficient in operation, and which may be manufactured on a commercial scale. that is to say one which is not so difficult to make as to be beyond the reasonable cost of such a contrivance.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim'without departing from the spirit or sacrificing any of the advantages of the invent-ion.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which l igure l is a rear elevation ot a radiator constructed in accordance with the present invention; Fig. 2 is a. section taken on line 2-2 of Fig. 1; Fig. 3 is a side elevation of one of the radiator sections; and Fig. 4 is a section taken on line -l-4 of Fig. 3.

In the drawings, the numeral 10 indicates the casing of the radiator, which is provided with an upper water chamber 11 and a lower water chamber 12. To the upper chamber leads an inlet tube 13 from the water jacket of the engine, while an "outlet tubel-l leads from the lower water chamber to the said water jacket. To the front face of the casing is dctachably fastened. in any suitable man ner. a frame 15. carrying a shield 16 of any preferred type. In the case illustrated in the drawings the shield is of the shutter type, comprising a plurality of slats 17. which are pivoted at 18 to the said frame and connected by links 19 with an actuating barQO, the

.latter'being shiftably disposed upon the frame 15. By means of this construction the degree of radiation of the device may be varied according to the requirements. The conduits through which the liquid flows from the upper water chamber to the lower water chamber are made, in the case illustrated in' the drawings, in the formof tubes 2i. arranged in a plurality of groups, each grhnpdieing independent of the others and connecting an inlet chamber 22 with an outlet chamber 23. In the case illustrated in the drawings. there are four inlet chambers and tour outlet chambers shown, although obviously any other suitable number may be employed, according to the, requirements. The tubes 21 run vertically. the inlet chamhers being disposed side by side as close as possible to the bottom of the upper water chamber 11 and the outlet chamber 23'side by side as close as possible to the top of the lower water chamber 12. Each inlet chamber is provided at its rear wall with a nipple 24 and each outlet chamber at its rear wall with a nipple 25. lVith the nipples 24 reg- Y ister nipples 26 on therear wall of the upper water chamber 11. and with the nipples 25' for instance there may be attached to the inlet chambers 22 and outlet chambers 23 blade springs 30 art. 31, respectively, .the free ends of which are hook-shaped, as clearly shown at 32, said hook-shaped ends bearing against the rear face of the radiator casing. v v

The operation of this device is as fol lows :The hot fluid flows from the upper water chamber 11 into the inlet chambers 22, through the radiator'tubes 21 into the outlet chambers 23, flowing from the latter into the lower Water chamber 12, and thence back to the water jacket of the engine; 15 Should any one of the radiator Sections become injured, that is to say should any one of the radiatortubes 21 become leaky, the said radiator section is disconnected from the circuit by removing-the respective conplings 28 and 29 and plugging up, in any suitable manner, the correspon ing ni pls26 and 27. The radiator, while its e ciency is thus decreased, can still be used while repairs are being made to the broken radiator section. For making the necessary repairs, the broken radiator section is removed from the casing.

' It is obvious that, while herein cooling conduits of a specific shape have been illus- 30 trated, an others may be used without dcparting .rom the invention, which lies mainly in the provision of a plurality of inlet chambers and a corresponding plurality of outlet chambers, connected by con duits, said inlet and outlet chambers being in communication with an upper water chamber and a lower water chamber, respectively.

What I claim is A radiator comprisin an upper water chamber, a lower water c amber, a plurality of inlet chambers having each a nipple, a corresponding plurality of nipples on said upper water chamber, a rubber hose between the nipple of each inlet chamber and the corresponding nipple of said upper water chamber, a plurality of outlet chambers corresponding in number to that of said inlet chambers, each outlet chamber being provided with a nipple, a corresponding number of nipples on said lower water chamber, a rubber hose between the nipple of each outlet chamber and the corresponding nipple on said lower water chamber. a plurality of conduits connecting each inlet chamber with its respective outlet chamber, a blade spring attached to each inlet chamber, and a blade spring fixed to each outlet chamber, the free ends of said springs being hook-shaped and bearing against the rear faces of the upper and lower water chambers.

Signed at New York, in the county of New York and State of New York. this 19th day of September, 1919.
